Local PT symmetry violates the no-signaling principle
Yi-Chan Lee, Min-Hsiu Hsieh, Steven T. Flammia +1
Bender et al. have developed PT-symmetric quantum theory as an extension of quantum theory to non-Hermitian Hamiltonians. We show that when this model has a local PT symmetry actin…
Asymptotic State Discrimination and a Strict Hierarchy in Distinguishability Norms
Eric Chitambar, Min-Hsiu Hsieh
In this paper, we consider the problem of discriminating quantum states by local operations and classical communication (LOCC) when an arbitrarily small amount of error is permitte…
Compatibility of state assignments and pooling of information
Todd A. Brun, Min-Hsiu Hsieh, Christopher Perry
We say that two (or more) state assignments for one and the same quantum system are compatible if they could represent the assignments of observers with differing information about…
When do Local Operations and Classical Communication Suffice for Two-Qubit State Discrimination?
Eric Chitambar, Runyao Duan, Min-Hsiu Hsieh
In this paper we consider the conditions under which a given ensemble of two-qubit states can be optimally distinguished by local operations and classical communication (LOCC). We…
A Return to the Optimal Detection of Quantum Information
Eric Chitambar, Min-Hsiu Hsieh
In 1991, Asher Peres and William Wootters wrote a seminal paper on the nonlocal processing of quantum information [\textit{Phys. Rev. Lett.} \textbf{66} 1119 (1991)]. We return to…
